build: use allowed over enabled

Meson feature options are typically in a tri-state of enabled, disabled,
or auto. The enabled and disabled functions on an option (from
`get_option`) no longer return true for auto features. Instead, the
expectation is to use `allowed()` which is true for both enabled and auto.

Switch all uses of `enabled` to `allowed`.

psu-ng: Remove previous input history code

As mentioned in a previous commit, the org.open_power D-Bus interfaces
that host the 30 second maximum and average input power values are no
longer necessary, and have been replaced by a single peak input power
sensor object.

Remove all of the code that dealt with them.

For now, the code remains that toggles the GPIO to sync up the input
history values between the power supplies on boots and plugs. As the
input history is used to populate the new peak sensor, its values across
power supplies will then be using the same time intervals.

meson: add necessary subprojects

Add subprojects for all the direct dependencies of the project such
that the project can be built outside of a Yocto SDK on a typical
Linux development system.

- Update the .gitignore to ignore the subproject source directories.
- Update the .gitignore to ignore alternative build subdirectory
names as is typical with most projects in the openbmc organization.
- Add wrap files for direct dependencies, copied from other
repositories that already have the same dependencies.
- Modify the meson.build dependency for libgpiod so that the C++
bindings are included.
- Add many missing dependencies throughout.
- Sort all dependencies alphabetically for consistency.

psu-ng: Power supply class updates for input history

Update the meson files to include the record_manager with the
phosphor-psu-monitor application.

Since we do not want to blindly enable input history for all power
supplies, base the enablement of the feature off of the driver name.
Change the PowerSupply class to require the driver name be passed in,
and pass that down via the PSUManager during the configuration
determination.

Add a server manager to the PSUManager to handle the INPUT HISTORY data
that will be under /org/open_power/sensors.

The INPUT_HISTORY command is handled via a sysfs file in binary format,
so add in a readBinary() base function to allow for mock testing.

psu-ng: Implement the PowerSystemInputs interface

Implement the PowerSystemInputs interface which contains the status of

Implement this interface under a /chassis0 path to specify it applies to
the current chassis. This can later be enhanced to support a
multi-chassis configuration.

psu-ng: Add in ability to get presence via GPIO

The device tree and entity-manager (D-Bus) properties have the power
supply GPIO presence lines named, so we can use those GPIO line names to
find the GPIO device to read for determining power supply presence.

Some systems have the power supply presence lines in a gpio-keys section
(notably IBM Rainier). To facilitate continued function while running
with a device tree that has not removed those device tree entries, allow
for a fallback to the old inventory D-Bus propertiesChanged or
interfaceAdded matches for presence.

psu: Updates for power supply presence

Update the JSON file to indicate the minimum and maximum number of power
supplies this system can have.

Update the JSON file to have an array of power supply objects, each with
their various own properties. Each power supply will have:
1) An associated D-Bus path for the inventory. This will have the
Present property.
2) An associated I2C bus number.
3) An associated I2C bus adddress.

Update PowerSupply class to have a present member variable, an
isPresent() accessor function, and two functions for updating the
presence. One function will be the call back function for either
inventory change events or interface added events, which will use
associated match member variables. The second function being one that
attempts to read the inventory Present property on startup. If reading
the Present property on startup fails, the property changed or interface
added events should work to get the value when that property is
available.
